Coarse-particle flotation applied to copper sulfide ores

• Feed Particle Size: This cell is being used industrially to float particles up to 6,000 µm (Phosphates). In the case of Cu sulfides, the ranges usually vary from 600 µm x 150 µm to 850 µm x 150 µm in some cases. • To optimize performance, it is recommended to work within a particle size distribution of 1:6.
